费米子流换位子中Schwinger项的两个符号

Two signs of a Schwinger term in a commutator of fermionic currents

J. S. Bhattacharyya

摘要:

我们考虑中心扩展的二维阿贝尔电流代数和维拉索罗代数和看到的符号的Schwinger项的变化,如果我们安排的交换子的傅立叶模式的正常相反的顺序。我们认为,这是允许的费米子的情况下,但不是在玻色子的情况下。

英文摘要:

We consider central extensions of two dimensional abelian current algebra and Virasoro algebra and see that the sign of the Schwinger term changes if we arrange the Fourier modes of the fermion in the commutator in the order opposite to the normal. We argue that this is permissible in the case of fermions, but not in the case of bosons.
